Pre-order data shows that more people have ordered the iPhone 7 Plus than the smaller 4.7-inch model. It’s the first time that the larger model has proven more popular than the regular one, with the dual camera the most likely explanation.

Apple never reveals the breakdown of iPhone models ordered, but Slice Intelligence has a huge panel of U.S. shoppers who agree to allow the company to roboscan their emails for purchase receipts and report the data. Analysis of almost 32,000 pre-order receipt emails reveals that the breakdown was 55% Plus, 45% regular. This contrasts with just 35% ordering the iPhone 6 Plus and 41% opting for the 6s Plus.

The company also collected data on the colors and storage tiers ordered …

Unsurprisingly, the vast majority of its panel members opted for one of the two new colours, Jet Black or Black. Interestingly, though, the matte black proved twice as popular as Jet Black, accounting for 46% of orders against 23% for the high-gloss finish. All other colors trailed significantly behind, as shown below.

Also unsurprising was the choice of storage capacity, with the vast majority – 67% – choosing the middle tier. While the percentage this time around was a little higher than usual, the middle tier is usually the most popular option for U.S. buyers.

While the dual camera system may have been the draw, it appears that the sensor on the second iPhone 7 Plus camera is smaller than the main one, and buyers will have to wait until later in the year for the shallow depth of field capability to be activated.
